Provides control of flow and return water temperature in an underfloor heating system in line with building regulation when using a high temperature system. Pre-assembled and tested to ensure that it can be fitted with minimum on-site labour required and commissioned immediately once fitted. Designed to connect to the left-hand side of a BAUSERV manifold as standard. The control group can also be altered to fit to the right-hand side of a manifold simply by switching the control group connections through 180°. The pump motor may need to be rotated through 180° to minimise the space occupied by the control group. Primary connections can be applied from the side or bottom of the control pack
